a circle is divided into 9 equal parts. That is the angle measure of two of those parts?
2(360/9) = ?
You probably forgot to mention that those equal parts are sectors of the circle (like slices of pizza)
each part would have a central angle of (360/9)° , so ......
carry on
To find the angle measure of one part when a circle is divided into equal parts, you need to divide 360 degrees (the total angle measure of a circle) by the number of parts.
In this case, the circle is divided into 9 equal parts, so we divide 360 by 9:
360 degrees / 9 parts = 40 degrees per part.
Therefore, each part of the circle has an angle measure of 40 degrees.
